Sulcus refers to a crease or invagination of the surface of the vocal fold. It is thought to be caused by a thinning or absence of a special layer of tissue, called the superficial lamina propria, which the vocal cord requires to vibrate in order to produce sound.

Nov 30, 2016 · Sulcus vocalis is used specifically to describe a groove or depression of mucosa along the medial surface of the true vocal fold that is typically found on the leading edge of the vibratory surface 1.

Acquired sulcus vocalis is thought to be much more common and occurs as a result of phonotrauma to the vocal folds (injury from voice misuse/abuse/overuse). The symptoms and treatment options for sulcus vocalis are the same as they are for vocal fold scar.

Vocal fold scar and sulcus vocalis may form due to unhealthy or inefficient voice use, intubation related trauma (from a breathing tube), history of laryngeal (voice box) infection, or radiation therapy. Some cases of sulcus vocalis may be congenital (present at birth).

Sulcus vocalis is a laryngeal condition linked to a clinically inhomogeneous defect of the covering epithelium with structural malformation of the vocal fold, ranging from minor invagination to the deep focal pits.

Sulcus Vocalis is a groove on the medial side of the true vocal fold. This inhomogeneous cover of the mucosa of the vocal ligament can lead to voice changes (dysphonia).

Jan 11, 2023 · Sulcus vocalis is a structural deformity affecting the vocal folds by the presence of a groove or depression at the edge of the vocal folds and is also called scarring of the vocal folds.

Oct 28, 2023 · The vocal fold bowing is highly suggestive of sulcus vocalis on videolaryngoscopy. In an attempt to reduce phonation effort and air leakage, muscular compensatory mechanisms appear, with vestibular fold hypertrophy being the most evident.

May 11, 2019 · Sulcus vocalis is an invagination of the vocal fold epithelium into the superficial lamina propria or deeper. Clinical presentation is characterized by dysphonia with vocal fatigue and vocal effort. The treatment paradigm for sulcus vocalis includes voice therapy and various open and endoscopic techniques.

Sulcus vocalis, like vocal fold scarring, is an indentation or retracted area on the vocal fold (cord) from scarring. It's sometimes called a hole in the vocal cord. The vocal cords are the structure that open for breathing, close for swallowing, and vibrate as air passes through to produce sound.
